THC Distillate

Before you read this very cool hack please understand that there are more than a few ways this can go wrong.  This blog post does not purport address all the possible safety concerns associated with its use.  Consult your safety officer for full professional guidance. High purity THC/CBD distillate will be very viscous. If it […]

Crystallization

Delta-9-Tetrahydrocannabinol (THC)  is a naturally occurring isomer of THC found in cannabis plants.  It’s psychoactive effects are well known.  While delta-9-THC is the most abundant isomer of THC, there is interest in the lesser studied delta-8-THC isomer.   IUPAC Naming Convention The diagram below has numbered positions on the top left ring structure.  If the […]

Optically clear THC distillate

Tired of chasing vacuum leaks, streaks and residual terpene smell in your THC distillate? Try spinning band distillation on your crude extract.   No leaks Stop chasing vacuum leaks and using globs of messy vacuum grease (vacuum grease is not food grade).  Spinning band distillation uses o-ring joints that are vacuum tight with every use.  […]

Compare Spinning Band Distillation with Short Path Distillation

Short Path Distillation Short path distillation is an introductory distillation technique sometimes used in labs in their start up phase. Short path produces usable but lower quality oil often in the 80% cannabinoid range after 2-3 passes. A common problem during short path operation are vacuum leaks which lead to degradation and dark oil. Spinning […]

THC Distillate Fraction Collector

Spinning band distillation separates the cannabis oil extract according to the boiling points of the components.     Mono-terpenes have the lowest boiling points, so they are collected first.  They can be found in the cold trap receiver due to their low boiling points. Residual ethanol is collected next in the fraction collector followed by […]

Spinning Band Distillation - High Purity THC Distillate

Spinning band distillation can produce distillate with very high THC/CBD concentrations.  Over 90% THC concentration is typical for a first pass. Some customers are routinely producing 98%+ cannabinoid distillates! How does the spinning band do it?   Distillation separates components by their boiling points.  This is commonly referred to as the “efficiency” of a distillation […]
